My electric useage is not counted towards CO2 output as Seattle City Light is the nation's only 100% Net-Zero electrical utility. In addition to using sustainable hydro-electric, I own 52 solar units in Seattle's Community Solar Program, which, so far, has re-paid me 15% of my initial investment. over four years. I expect to break even in about 2022.

​I also don't include my food carbon footprint, though I should, because I have no idea how to document in detail everything I eat. I regret I am not a vegetarian- but I can't do wheat or dairy so this makes things complicated. I do try to eat only local, organic meat, mostly chicken. I do try to shop at Farmers' Markets, even though this gets complicated by travel. I do try to grow veggies at home in the summer.
